CAR-DOOR.

Specification of Letters Patent.

Patented Sept. 23, 1913.

Application filed August 7, 1911. Serial No. 642,635.

To all 107mmz't may concern:

Be it known that I, Cimnnns E. Siuvnirr, a citizen of the United States, residing at Council Bluffs, in the county of Pottawattamie and State of Iowa, have invented certain new and useful Improvements in Car-Doors, of which the following is a spceilication.

This invention relates to car doors, and has for its object to provide an improved door of this character which may be readily and conveniently applied to an ordinary box war without requiring any material change or alteration therein beyond some slight additions for the mounting of the door.

The present door is designed to be mounted upon the interior of the car, and to serve as a grain door. It, may be employed in conjunction with the ordinary outside door, and the ordinary outside door omitted and the present door only employed.

lVith these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fullv described, shown in the accompanying drawings and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size and minor details may be made within the scope of the claims, without departing from the spirit of the present invention.

In the accompanying drawinqs;Figure 1 is an elevation, looking from the exterior of a car, of a door constructed in accordance with the present invention. Fig. 2 is a de' tail sectional view taken on the line 22 of Fig. 1. Fig. 3 is an elevation, looking from the interior of a car, of a door constructed in accordance with the present invention and on a scale smaller than that shown in Fig. 1. Fig. l is a detail sectional view on the line l l of Fig. 8. Fig. 5 is a detail sectional view on the line 55 of Fig. 3, the upper door member being shown swung outwardly in dotted lines. Fig. (3 is a view similar to Fig. 3 showing the upper door member slid to one side of the door way, and the lower door member swung or tilted to the opposite side of the doorway. Figs. 7 and 8 are enlarged detail views showing the device for locking the upper sliding door section in its closed position. Figs. 9 and 10 are detail fragmentary views showing means for locking the wickets of the upper and lower door members. Fig. 11 is an enlarged detail sectional view taken on the line 1111 of Fig. 3.

Like characters of reference indicate corresponding parts in each of the several ligures of the drawings.

The present invention includes an upper door member 1 and a lower door member 2, the upper door being mounted to slide horizontally in a direction longitudinally of the car to open and close the upper portion of the door way, while the lower door member 2 is mounted to swing or tilt vertically to one side of the doorway, so as to open and close the lower part thereof. The side 53 of the car is of ordinary ctmstruction and has an ordinary side doorway or opening t, as clearly shown in Figs. 2 and 4-.

The lower door member 2 consists of a single metal plate or sheet of suitable size to close the lower portion of the door ay, preferably the lower half thereof, and this door member is stiffened and strengthened by intermediate angle bars 5, and upper and lower angle bars 6 and 7 secured to the outer face of the door. Upon the top of the horizontal member of the upper angle bar or iron is a facing strip 8, preferably of wood, the upper face of which is beveled downwardly and inwardly of the car as best shown in Fig. 5 of the drawings. This lower door member is pivotally supported at one of its lower corners, here shown as the lower right hand corner, looking from the interior of the ear. To effect this pivotal mounting of the door, the latter is provided with a lateral extension or heel S) which is hinged or pivoted in a suitable bearing 10 secured to the floor of the car, whereby the door may be swung or tilted upwardly and to the right, as indicated in Fig. 6 of the drawing. For the purpose of guiding the door in its tilting movement, there is provided an arcuate guideway 11, preferably in the form of a quadrant secured to the inner side of the car and spaced therefrom, said guideway being slidably engaged by a guide member 12 at the upper right hand corner of the door, this guide member working against the guideway and thereby hold ing the door from swinging away from the side of the car during tilting movements of the door. By preference, this guide mcma suitable extent. When the tilting door2 her 12 is in the'form of a Z-bracketso as to engage beneath the guideway 11 and between the latter and the side of the car. The.

convened edge of the guideway is toothed, as shown and 1s engaged by a gravity detent 13 pivoted to the upper right hand cornerofi the door member, whereby the door may be held in any tilted 'position, as indicated-by dotted linesin Fig. 6, so long as the center of gravity of the door is at'the left hand side of the'pivotal support of the door. The

guide'bracket 12 and 'the'detent'13 are carried by a lateral extension l lofthe upper. right hand corner of the door nenibe'r -2.j When the door member 2 has been swung to its open position, theexte'nsion 12 rests against the floor of 'thecan'whilethe other corner of the door engages back of the keeper 15 securedfto the inner side of the car.

the car in positionxto engage what is the upper edge of the door member in its "open position, as cle'arly'shown 1n F g. 6 of the" drawing. Any suitable handle'a is provided upon the inner side ofthe door-member 2for swlnging the same into open and closedposition;

It will here be note'dthat-,'at each end'of the guideway 11, the teeth are omitted for.

is moved into its closed position, the swinging dog'or detent 13e'scapes from theteeth.

at the upper end of'theguideway'and hangs vertically in the seator recess provided at the upper end of the. guideway by the omission of the teeth, whereby thede'tent is position to reengage the teeth ofthe guideway when the door'ls againswung open and be in a position to hold th'e door in any tilted Whenthe door is swung to ltS open posltlon, the detent'ag'am escapes from position,

the teeth at the lower end-oftheguid'ew'ay, and 1s free to reengage'theteethwhen the door istilted back to its closedpos'ition. The

provision of teeth upon the 'guideway 11 is also a very important feature, when it is.

considered that the door is veryhea'vy and is accessible for opening from the exterior of the car only. A fterj'the car'has beenparti ally unloaded through the wicket '37 and the door 1 slid horizontally into an open, position, the lower 'tiltalo'le door ma'y opened to'a slight extent by pryingizp the same fromthe exteriorof the car. As the door is pried up' a little at atime the detent 13'will' engage the teeth onthe gu'i'deway' and thereby holdthe door from'droppingbaclz, into its'clo'sed position, which obviates' the necessity ofmanuallyholding'the door-while prying it open. p

To eii'ect'a grain tight fit'of the lower doo member 2 with the sides ofthe doorway, "the free edge of the'door, which is opposite the the door member.

To prevent oscillation of the tilting door'ln its open position, a swlnging-g'ravltyj detent 16 1s pivoted to the inner side of the 'car. from the strips '29, th'e door member is swung inwardly upon'the guideway 27 as a 'cal stl' ip'2ls'ecuredto the inner side of the car, the meeting faces of these stripsbeing beveled so as to for'ma tight joint.

i The upper door member 1 is 'made up of a single 'metalsh'eet or plate,and is stifliened and strengthened by intermediate transverse angle-irons or-ba rs 22 and upper and lower anglebars 23 and 24. Upon the lower face of the lower angle bar 24 is a wooden strip 25 having a beveled face which fits tightly against the beveled face 8 of the wooden stripupon the top ofthe lower door member so as to form grain tight fit betw'een the meeting edges of the door members; S-uitable hangers 26' are provided at the upper corners of thedo'er member 1, and these hangers have a sliding and rotatable fit upon aguideway27 secured to the inner side of the'carand extending across the top of the doorway "and for a suitable distance beyond one sidethe'reof opposite the=pivotal' support of the lower door mem'ber.

To eiiect ati'ght joint between theupright edges'oit' the upper door member -1 and the sides of the car, in the closed position ofthe door, beveled strips'28 are secured to the outer face of thedoor member-at its upright edges so as 'to engage correspondingly-beveled strips 29 secured to the inner walls oi To disengage the door member support, asindica-ted by dotted lines in Fig.

5 of the drawing, whereupon the door mem' ber may he slid upon the guideway and movedto one sideotthe doorway'to'the position shown-in Fig. 6. AsuiItable-h'andle30 is provided upon the inner side of the door member 1 for manipulating the door, and'a handle ih'shown in Fig. 1, is provided-upon theout'ersideof the door forconvenience in m'anipulatingitfromthe exterior of the car.

To *locl; the upper door member in its closed position, there is provided, as best shown in Figs. 7 and 8, a pivotal latch 32 mounted upon onset the door posts and designedto engage'a. keepert provided upon the outer side of the" upper door 'member '1,

there being a swinging'detent pivoted to theouter face ofthe' doormember above the keeper in position to engage the top of the latch 32 and" hold itdo'wn in the keeper.

The detent: Mandthe latch 32are provided with ears '35 and 36 respectively, having alined perforations for the reception any commoner preferred form of seal',such for instance as the ordinary wire seal employed for sealing box cars. It will of course be understood that one of these latch devices is provided upon each door post, as plainly indicated in hi 1 and 6 of the drawing.

When the two door members are in closed position, the lower door member is held against accidental tilting by reason of the fact that the upper door member engages snugly across the upper edge of the lower door member, and as the upper door member is held against accidental movement by the two latches 32, the two door members are positively held in closed position.

To open the door, the latches 32 are disengaged from the keepers, and the upper door member is then swung outwardly to disengage the strips 29 and then the upper door member is slid to one side of the doorway, after which the lower door member may be tilted to its open position shown in Fig. 6.

The lateral extensions 9 and 14 bring about an important feature, in that any slight accun'iulation of grain, coal or the like adjacent the pivotal support of the tilting door will not prevent the complete opening of the door, for the reason that the lateral extensions 9 and i l hold the intermediate edge portion of the door above the floor oil the car in the open position of the door. llloreover, the lateral extension 14 will crush small accumulations oil. grain, coal or the like, by reason of the considerable weight of the door, and thereby permit the door to open to its complete extent.

The upper door member is provided with a wicket 37, and the lower door member is provided with a wicket 38, each of which is suitably hinged to its door member, the wicket 37 bein hinged at its lower edge, and the wicket 38 hinged at its upper edge.

For holding each wicket in its closed position, any preferred latch means may be employed, a suitable arrangement being shown in detail in Figs. 9 and 10. At each upright edge of the wicket there is a latch bar 37 which projects beyond the free edge of the wicket and is designed to be engaged back of a vertically movable gravity bolt 38 working in a suitable casing 39 provided upon the adjacent door member, the lower end of the bolt projecting below the casing having a beveled lower end portion l-O across which the latch member 37 wipes. during the closing of the wicket so as to lift the bolt, said bolt afterward dropping down in front of the latch to lock the wicket. The upper projecting end of the bolt is provided with a transversely extending headed handle ll, which may be engaged with a swinging link 4-2 carried by the door so as to hold the bolt in an elevated position when it is desired to open a wicket.

For convenience in opening the bottom tilting door member 2 from the exterior of the car, a suitable handle t?) is provided upon the exterior of the door member, as best shown in Fig. 1. oil the drawings.

The engagement of? the guide bracket 12 of the door 2 with the arcuate guide it will be best understood by reference to Fig. ll of the drawings, wherein it will be seen that the guide bracket 12 extends laterally from the floor and is provided in its upper edge with a seat or socket 12 receiving the lower concaved edge of the guide. By this means the door 2 is held in a vertical plane and prevented troni swinging sidewise away from the side of the car.
